稻鸭共作与圈养模式对麻鸭生长性能影响的比较研究

A Comparative Study Between the Effects of Rice⁃duck co⁃cropping and captivity on the Performance of Hemp Duck

该研究旨在比较研究稻鸭共作和圈养两种饲养模式对麻鸭生产性能的影响,为稻田养鸭生态模式提供理论和技术支持。选择来自一个商业孵化场的400只雄性1日龄麻鸭随机分为稻鸭共作组(密度为30只鸭/亩)和圈养组(密度为10只/平方米),每组10个重复,每个重复20只,试验时长49天。圈养按20只鸭子分组分配到10个铁丝地板围栏,共200只;另外200只在稻田放养。在49日龄时,分别测定这两组鸭的体重、采食量等生产性能。结果表明,稻鸭共作组日增重、日采食量、体重均显著高于圈养组(P<0.001),而圈养组料重比高于稻鸭共作组(P<0.001)。该研究结果表明,采用稻鸭共作模式有利于提高蛋鸭生产性能,降低饲料消耗,提高经济效益。

This study aimed to evaluate and compare the effects of rice-duck co-cropping and captivity on the performance of hemp duck,in order to lay a theoretical basis for the ecological farming of ducks.A total of 400 one-day-old male ducks from a commercial hatchery were randomly divided into two groups:a rice-duck co-culture group(density of 30 ducks/m2)and a captive group(density of 10 ducks/m2),with 10 replicates in each group and 20 ducks in each replicate.The experimental duration was 49 days.The 20 ducks were divided into 10 wire floor fences for a total of 200 ducks in captive group,and another 200 were stocked in paddy fields as rice-duck co-culture group.At the age of 49 days,performances including body weight and feed intake were measured.Results showed that the daily gain,daily feed intake and body weight of the rice-duck co-culture group were significantly higher than those of the captive group(P<0.001),while the feed-to-gain ratio of the captive group was significantly higher than those of the rice-duck co-culture group(P<0.001).In conclusion,the rice-duck co-culture model could improve performance of ducks,reduce feed consumption,and improve economic profit.
